DO
Use ocean blue #0069FF for brand, CTAs, and links
Use green #15CD72 only for healthy / active resources
Set IPs, regions, sizes, and commands in the mono stack
Keep the canvas cool off-white / navy so status colors read
Show region and size on every Droplet
DON'T
Don't drift the blue lighter — the brand blue is #0069FF, not #0080FF
Don't invent dark surfaces; anchor on the real DO navy #080B2D
Don't use green for anything but healthy / active state
Don't set IPs or resource sizes in a proportional font
Don't hide a Droplet's status while it's provisioning
